AUTO 112 FINAL EXAM
(AUTOMOTIVE BRAKE SYSTEMS)
2026/ 2027 | 100% Verified with
Correct Questions and Answers
1. A defective vacuum brake booster will cause a:
Correct Answer: Hard Brake Pedal
2. Two techs are discussing vacuum brake boosters. Tech A
says that when the brakes are in the applied position,
vacuum is present on the front side of the diaphragm.
Tech B says that when the brake is applied with great
force, some vehicles have a Brake Assist System (BAS)
that opens a valve at the back of the booster to increase
atmospheric pressure and increase booster performance.
Which tech is correct?
Correct Answer: Both Techs
3. A hydraulically operated booster unit stores fluid under
pressure by means of:
Correct Answer: An accumulator
, 4. When blowing through the vacuum supply hose, if air
passes through the check valve into the booster:
Correct Answer: Replace the check valve
5. Tech A says that the ABS may not result in a shorter
stopping distance compared to brakes without ABS. Tech
B says that a pulsating brake pedal during normal braking
is a characteristic of most ABS-equipped vehicles. Which
tech is correct?
Correct Answer: Tech A only
6. Two techs are discussing ABS wheel speed sensors. Tech
A says that some ABS systems use a sensor located in the
rear axle pinion gear area. Tech B says that all ABS
systems use a wheel speed sensor at each wheel. Which
tech is correct?
Correct Answer: Tech A only
7. A passive wheel speed sensor is also referred to as a:
Correct Answer: Variable Reluctance (VR)
8. Which part of an antilock brake system is used for tire
pressure monitoring?
Correct Answer: Wheel speed sensor
